Abstract: The hammer has two handles (11, 12) projecting transversely from the housing (1). Said handles are attached to the free ends of a leaf spring (10) bent in a Z-shape. The bends (13, 14) of the spring (10) wind round rollers (15, 16), fixed to the housing, with play. A pusher (22) is pivotably mounted on one handle (11). It has a connecting link (27), the centre of curvature of which coincides approximately with the centre of pivoting (26) of the associated handle (11) when the pusher (22) is actuated. The connecting link (27) actuates, via transmission members (31, 32), a valve pin (5) of the hammer. As a result of this design, the handles (11, 12) can be effectively protected not only from the base frequencies, but also higher-frequency vibrations of the hammer. Even when pulling the hammer, this design is at least partly effective. <IMAGE>

Abstract: A low-frequency power amplifier (10) with an integrated BTL output circuit (20) drives a load (SP). The amplifier (10) incorporates a bias circuit (11) for supplying a bias voltage to each circuit composing the amplifier (10), a control circuit (12) for switching between the normal operation mode and the mode for detecting the load being in an open-circuit condition, a detector circuit (13) for detecting the load (SP) being in an open-circuit mode by supplying current to the load (SP) and sensing the current flowing through the load (SP), and an output circuit (14) for telling an external circuit of the integrated circuit that the load is in an open-circuit mode. All these circuits (11, 12, 13, 14) are squeezed into a single chip. The control circuit (12) controls the bias circuit (11) and detector circuit (13). During normal operation, the BTL output circuit (20) is in an operative state, while the detector circuit (13) is in a nonoperative state. When the load (SP) is detected being in an open-circuit mode, the bias circuit (11) is forced to stop operation, which causes the BTL output circuit to stop operation, thereby enabling the detector means (13) to sense that the load (SP) is in an open-circuit mode.

Abstract: A power steering control valve assembly includes inner and outer valve members (40,42) and a force transmitting assembly which resists relative rotation between the valve members. The force transmitting assembly includes an upper reaction element (116) which is connected with the inner valve member, a lower reaction element (126) which is connected with the outer valve member and a plurality of force transmitting elements (120) or balls which are disposed between the upper and lower reaction elements. The balls engage recesses in the inner valve member (40) and rotate with the inner valve member. The balls also engage recesses formed in the lower reaction element (126). In one embodiment of the invention, only three balls are utilized. Hydraulic and mechanical balancing of the power steering control valve is attained by hydraulically balancing the inner and outer valve members before connecting the lower reaction element with the outer valve member. Thus, the lower reaction element is loosely positioned relative to the outer valve member. The upper reaction element urges the balls against the lower reaction element to accurately locate the lower reaction element relative to the inner valve member. The outer valve member and the lower reaction element are then interconnected by deforming a portion of the outer valve member.

Abstract: A personal data card (10), also known as a smart card, comprises a lamination of thermoplastic sheets. One sheet (140) is a circuit board made from polyester film having metallic interconnection paths (144) on its surface formed by etching. Smart cardd circuit, including one or more frangible semiconductor chips (200), are mounted on the circuit board. Another sheet (130) is a structural (strength) member which comprises polyester film that has been heat-stabilized and includes a heat-activated adhesive (133) on both sides (131, 132). The structural member has through-holes (136, 137) for receiving components (200, 500) mounted on the circuit board when these sheets are brought together, and for admitting an epoxy encapsulant (300, 400) poured therein. When the encapsulant cures, it is much more rigid than the polyester card body and thus protects the semiconductor chips from breaking when the card is bent. Top and bottom sheets (110, 150) of the smart card comprise thin films of polyvinyl chloride that protect the card from external contaminants and have identical thermal expansion chacteristics so that the laminated structure does not warp with changing temperatures.
